This is as good as it gets for the year and price, I am picky and have no complaints other then a weak remote, oh well everything cant be perfect.
I've had this unit for 16 months now. I have seen many issues concerning this problem from other customers. This is a major design flaw for Samsung not to correct. The TV tries to turn on but can't. 16 months is far to short of operation for a $2500 product. I can hear it clicking to power up but never happens. Though I was very happy with the image initially I now have power issues. The typical solution is to have it serviced and pay $500 for a new part.
It simply keeps clicking with no picture. I've tried unplugging the unit and then trying again but that hasn't helped. Since this is an inherent design problem they should service these as if under warranty. I can't recommend this product.
First I will say that hands down for the price this set has one of the finest pictures around.And now the bad news - either the quality control or effort in design is horrible. But for the majority it means shelling out a few hundred dollars to get fixed.Will I buy another Samsung - cannot say for sure if it is worth the trouble.By comparison I have a smaller Vizio LCD quite a few years old that is on all the time and has a nice picture - not once has it ever given us a problem. A very common problem with Samsung electronics is to use cheap components and in some cases undervalued components.The Power Supply board is known to generally fail within thirteen or so months due to blown capacitors. In the circuit where 16 to 25 volt caps should be placed Samsung selected to put just 10 volt and the results are blown caps in a very short time frame.The fix for anyone familiar with how to replace board components is relatively easy as this board in question is very accessible from the back of the set. I think the next round is going to be reliability vs. picture quality.
We purchased this set July 11,2008 from Amazon and have been very satisfied until recently. Here is the link, although it might get deleted: [.].I am going to see if the problem gets worse and will attempt the repair myself if needed, being adventurous (and chea - er, thrifty). Total cost: $1.79The back was easy to remove and the circuit board was right there, with no cage to remove. A little research revealed this is a very common problem with Samsung LCD sets and is frequently caused by capacitors on the power supply board going bad. My soldering skills are rusty so I had a neighbor remove/replace the caps. Naturally, it only happens after the set is out of warranty, so the repair is several hundred dollars.The failed capacitors are usually detectable visually and many folks have successfully completed the repair themselves for a few bucks (new caps and maybe some soldering tools), according to a tech report web site. About one week ago, the unit started to cycle on and off a few times at start up. I will post follow ups.This is a real shame because we really love the set - note the attributes are all five stars.Followup: Replacing the two 1000uF 25V capacitors (CM851 and 852) fixed the problem.
You do have to lay the set down to take the back off in order to get to the circuit board. This site contains detailed instructions and pics and links to videos. The taller two 1000uF caps were distorted at the top and one had just started leaking black stuff. Really, really simple fix.
I purchased it anyway, and are now suffering with the rest of those poor souls that experience problems with the unit having their capacitors burning out, as well as the unit turning itself off/on sporatically. I bought this unit back in May 09'. I had indeed, looked over all of the posted comments concerning the Samsung LN52A650A1F. The Samsung Technician has been by here so many times, we've become best friends. Yes, for Pete's sakes, DON'T BUY THIS UNIT.
